The "A" in the beginning of the search result means that the result is an answer, not a question. The first result in your search is the question itself; the second is an answer to that question. Since they are both physically located on the same page, you're thus redirected to the same page.
What's supposed to happen once you tap on the answer link is that it should scroll you to that answer. But I've often seen in the desktop site that if a question has a lot of answers, the page doesn't scroll until it has fully loaded (which can take some time). I'm not sure if that's what's happening in the mobile app (it looks like you're using the iOS app from your screenshots), or if there's some bug that's preventing it from scrolling, but the mobile apps are no longer being actively developed so we can't know for sure.
